Accusoft ImageGear contains two remote code execution vulnerabilities. ImageGear is a document and imaging library from Accusoft that developers can use to build their applications. The library contains the entire document imaging lifecycle. These vulnerabilities are present in the Accusoft ImageGear library, which is a document-imaging developer toolkit. An adversary could exploit any of these vulnerabilities to cause various conditions, including an out-of-bounds write, to eventually execute code.
In accordance with our coordinated disclosure policy, Cisco Talos worked with Accusoft to ensure that these issues are resolved and that an update is available for affected customers.
